COKE-BREAKER.

FPECIFICATION forming part of Letters Patent No. 353,011, dated November23, 1886.

Application filed April 28, 1886.

To all whom it may concern.-

Be it known that I, BENJAMIN J. ALLEN, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Coke-Breakers; and I dohereby declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

The object of this invention is to provide a device better adapted forbreaking the coke formed in the manufacture of illuminating-gas intopieces convenient for stove purposes, one that will enable the operatorto break the coke with greater facility, and so that the pieces will bemore uniform in size, and one which may be readily sharpened after theteeth have become worn with use.

Theinvention consists in the improved cokebreaker having thearrangements and combinations of parts, substantially as willbehereinafter set forth, and finally be embodied in the clauses of theclaims.

Referring to the accompanying drawingfin which like letters indicatecorresponding parts in each of the figures, Figure 1 is a side elevationof the improved breaker.- Fig. 2 is a face view of the head thereof, andFig. 3 is a sectional view of said head taken through line 00.

In said drawings, a indicates the head of the hammer or breaker, and bthe handle thereof. Said head is preferably a casting of steel havingradial breaking-teeth c 0, extending from the periphery din manydirections, the said teeth lyingin laterally-adjacent pairs, as shown inFig. 3, and flaring oppositely and outwardly, so that at their'pointsthey will lie a considerable distance apart, and thus take in or form.

a lump of suitable size for an ordinary stove or furnace. Said teeth aredrawn out to form long but narrow teeth capable of cutting into thecoke, so that -in their effect is rather to formincisions in the cokeand then Wedge the same apart into smaller portions than to pulverize.The head of the breaker being of metal and preferably of steel, theteeth, after having been worn down by use, may be drawn Serial No.200,429. (No model.)

out again by ablacksmith by any suitable forging process, so that itsuse can be continued indefinitely.

Inasmuch as the area surrounding the retorts are paved with flagging andthe coke to bebroken is first dumped or dropped thereon,

always present themselves to the coke in the breaking process, so thatthe pieces resulting froma blow will approximate a uniform size. By thisconstruction the operator is compelled when employed in breaking thecoke to present teeth thereto, and cannot present any flat or blunthammer-like surface liable to break the coke into powder or very smallbits should he carelessly allow the hammer or breaker to turn in hishands.

Through the center of the head is formed a perforation, e, to receivethe handle b, which latter extends from the said head in a direction atright angles to the plane of its face, as will be understood uponreference to Fig. 1.

Bythe construction described the operator in handling the hammer orbreaker after the cokehas been dumped upon the flagging above referredto and cooledby water, and before it is carted away, walks around theheap,and,selecting his lump, strikes the same with four prongs or teethat a time, causing the said lump to be broken'into pieces of about asize equal to the distance of the teeth apart.

I'am awarethatin PatentNo. 198,459 ahandled head is shown having groovesand notches on a peripheral face thereof, said head being made ofpotters clay and adapted for use in making beefsteak tender; but saiddevice,for reasons already stated, would not serve the purposes of acoke-breaker, as will be evident.

What I claim as new is- V l. The improved coke-breaker hereinldescribed,consisting, essentially, of a metallic head having teeth formed in pairsradially therearound and a handle, said parts being constructed,arranged,-and combined substan- 2. In combination, a metallic headhaving In testimony that I claim the foregoing I long andoppositely-flaring teeth arranged or have hereunto set my hand this 27thday of formed radially andin pairs around the periph- April, 1886. eryof said head, and having a central opening 5 for a handle, and ahandle,all said parts being constructed and arranged substantially as and forthe purposes set forth.
